Optimal Currency Hedging for International Equity Portfolios

We explore currency exposures in international equity portfolios by decomposing the optimal currency portfolio into a “hedge portfolio,” which minimizes equity volatility, and an “alpha seeking portfolio” based on the well-documented currency styles of value, momentum and carry.


Characteristics Are Covariances: A Unified Model of Risk and Return

We propose a new modeling approach for the cross section of returns that helps determine whether excess returns to factors are driven by compensation for risk, or an anomaly effect.


Empirical Asset Pricing via Machine Learning

We show how the field of machine learning can be used to empirically investigate asset premia including momentum, liquidity, and volatility.

The Tax Benefits of Relaxing the Long-Only Constraint: Do They Come from Character or Deferral?

Are there tax benefits from relaxation of the long-only constraint? If so, what are the sources? To answer these questions, we decompose the total tax benefit (or liability) of a strategy into two components.

Risk Adjusted Performance of Middlemen in Housing Markets

Do housing market asset flippers outperform? We study the risk-adjusted returns of asset flippers operating in the housing market of Los Angeles County with respect to both investments in the U.S. stock market and in a passive mutual fund tracking a representative U.S. REIT index.


Being Right is Not Enough: Buying Options to Bet on Higher Realized Volatility

Should investors who buy options expect to profit when realized volatility increases? If so, under what conditions? To answer these questions, we analyzed the relationship between long volatility performance (buying options) and contemporaneous changes in volatility.

Using live trade data from a large institutional money manager over a 19-year period, we find actual trading costs to be an order of magnitude smaller than previous studies suggest.
